Association Between Carotid Arterial Strain and Heart Rate Variability in Older Age
The Journal of Clinical Hypertension, Volume 28, Issue 6, June 2026.ABSTRACT Loss of the normal heart rate variability (HRV) predicts death. This study investigated the association between carotid arterial strain (CAS) and HRV in an older age population‐based cohort. We hypothesized that impaired arterial compliance and increased vascular stiffness could inhibit the baroreceptor reflex, resulting in cardiac autonomic ...

Determination of left atrial volume in healthy dogs and dogs with myxomatous mitral valve disease
Pesquisa Veterinária Brasileira: The left atrial volume (LAV) can be obtained using the biplane Simpson's method via echocardiography. Although in medicine this parameter has been considered to be a prognostic marker of left atrial enlargement in several cardiac diseases, in dogs with
